Written by the team behind Flash. Flash is one of the tools compared below, so this is a founder-disclosed comparison, not an independent review or hands-on benchmark.
Last checked: November 2026. Sources are each vendor's own public pages, checked on 10 November 2026. Confirm anything important in a demo and with your accountant.
General information only. Not tax, legal or accounting advice. Income recognition, cost basis, depreciation lives and tax filing are decisions for you and a qualified adviser in your jurisdiction.
Flash is the CFO layer for compute operators: Bitcoin miners and GPU hosting businesses side by side.
Short verdict
Evaluate Flash when you need mining-site economics, hardware book depreciation, reviewed QuickBooks entries and a pack your lender can check. Evaluate Clams when you need a Bitcoin ledger you can run yourself, watch-only payout wallets, a local CLI or self-hosted Server, and journal or CSV exports for downstream tools. There is no universal winner. This page covers only what each vendor's public pages state.

Comparison table
| Topic | Flash (public pages) | Clams (public pages) |
|---|---|---|
| Record sources | Braiins Pool (read-only API token), OCEAN Pool (public mining address), NiceHash mining earnings and wallet activity, and direct Kraken, Coinbase, Coinbase Prime and Gemini connections. Luxor and Foreman are CSV import only [1] [2] | Watch-only payout wallets (xpubs, descriptors or addresses) synced on demand, plus custom CSV mapping of pool statement exports [3] |
| On-chain, Liquid and Lightning | On-chain Bitcoin wallets. Customer payments can include BTC and Lightning; that is a payments feature, not a Lightning-node ledger claim [1] [2] | On-chain Bitcoin, Lightning nodes, and Liquid L-BTC and issued assets such as Liquid USDt on the same ledger [4] |
| Hardware depreciation | Straight-line book depreciation from the fleet register you record; journal entries to review before QuickBooks [1] | Not stated publicly on the pages reviewed [3] [4] [5] [6] |
| Site economics | Profit by site and machine group; break-even by site; fleet register by model [1] [2] | Not stated publicly on the pages reviewed. A Lightning node profitability report is documented; that is not ASIC-site profit [3] [4] |
| Downstream journal entries | Direct QuickBooks connection: mapped expenses into the close for review, then reviewed entries you post [1] [2] | Journal-entry and CSV exports for downstream accounting tools or tax software. A native QuickBooks connection is not stated on the pages reviewed [4] [8] |
| Deployment | Web application with log-in on the public product pages. Self-hosting and a local CLI are not described there [1] [2] | Local CLI or a self-hosted Server, with role-based access, workspaces and profiles [4] [6] |
A source-coverage demo is still required for your wallets, pools, policy and ledger.
Flash: mining-site economics into reviewed QuickBooks books
On the live mining page, Flash turns pool payouts and exchange activity into a monthly close. Each payout is valued when received, matched to the site that earned it, and held with the costs you file and book depreciation from the fleet register. Profit and Bitcoin break-even appear by site. You review before anything posts to QuickBooks. [1]
Live connections are listed in the table above, including NiceHash mining earnings and wallet activity, including deposits, trades and withdrawals. Luxor and Foreman are CSV import only. RunPod is not an integration. [1] [2]
The QuickBooks handoff: bring mapped QuickBooks expenses into the close for review; check site costs, depreciation and Bitcoin cost basis; then post the entries. Invite your accountant with read-only access. A locked month produces a pack your lender can check, shaped with lender feedback. Flash does not replace your accountant. [1]
GPU hosting businesses use the same positioning for profit by site and machine group. Vast.ai is in early access: a read-only key brings in machine inventory, earnings, platform fees and payouts. Review earnings and fees by machine, and confirm each payout when the money arrives. Payouts are checked separately from earnings so income is not counted twice. See Flash for GPU operators for that workflow. [7]
Clams: a Bitcoin ledger you can run yourself
Clams' miners page describes watch-only payout wallets, a one-time mapping of pool exports, and books you can review with an accountant. Add payout wallets as watch-only xpubs, descriptors or addresses, then sync on demand. Pool statement exports use a custom CSV mapping. Each payout is valued at the Bitcoin price on the day received, and mining income is categorized separately. Jobs can be scheduled with cron via the CLI. [3]
The features page documents a double-entry ledger, FIFO, LIFO and HIFO, and journal-entry and CSV exports for downstream accounting tools or tax software. Internal moves between your own wallets are detected so they are not double-counted. Lightning node connections, a Lightning node profitability report, and Liquid L-BTC and issued assets such as Liquid USDt are also documented. That Lightning report is routing income and channel costs, not ASIC-site operating profit. [4]
You can run a local CLI on your own machine, or deploy a self-hosted Server in your own infrastructure. Role-based access, workspaces and profiles are documented. [4] [6]
The integrations directory lists Coinbase, Gemini and Kraken as CSV (custom mapping). No QuickBooks, Xero or NetSuite connector is named on the integrations, miners or features pages reviewed. [8] [3] [4]
Clams' pricing page states that the Standard tier is free, with unlimited people, profiles, wallet connections, transactions and reports, and that Enterprise is custom quoted by scope. This page does not compare Flash plan amounts. See Flash pricing. [5]
Hardware depreciation and ASIC-site operating economics are not stated publicly on the Clams pages reviewed. That is not a confirmed No. Ask for a demo of site allocation or an equipment register if they matter to you.
Worked month: what either vendor should explain
Illustrative only. Invented amounts, not a customer result, not a current Bitcoin price and not tax advice.
Received mining income valued at $10,000. Later, those coins move from the payout wallet to another wallet the business already owns. Recorded power $5,000, hosting $1,000, book depreciation $1,000. Result before other costs and tax, if the transfer is not treated as new income: $3,000.
Ask each vendor to show the source and receipt value for the $10,000; how the later wallet transfer is classified so the original receipt value is preserved and the move is not booked as new mining income; how power, hosting and the $1,000 depreciation are assigned; and which reviewed QuickBooks entries, or Clams journal or CSV export, your accountant would use. Neither vendor was tested against this worksheet.
Who should pick Clams
Keep Clams on the shortlist when you want a Bitcoin ledger you run yourself, on a local CLI or a self-hosted Server; when the core workflow is watch-only payout wallets and custom CSV mapping of pool exports; when you need journal-entry and CSV exports for downstream tools; or when books must also cover the Lightning or Liquid activity Clams documents. Confirm current Standard-tier terms on Clams' pricing page. [3] [4] [5] [6]
Who should evaluate Flash
Evaluate Flash when you need profit by site and machine group, break-even by site and book depreciation from a fleet register; when the close ends in reviewed QuickBooks entries; when you want the live pool and exchange connections listed above; or when you need a pack your lender can check, shaped with lender feedback. [1] [2]
If both scopes matter, shortlist both and run the worked-month checklist. Exact pool coverage and export layouts were not verified here. This page uses no testimonials, ratings or time-saving claims.

FAQ
Is there a native QuickBooks connection in Clams?
Not stated publicly on the pages reviewed. Clams does document journal-entry and CSV exports for downstream accounting tools or tax software, which is not the same as a native QuickBooks connection. Confirm the import layout your ledger needs in a demo. [3] [4] [5] [6] [8]
Are pool APIs the same as a custom CSV mapping of pool exports?
No. A direct pool API and a file import are different methods. Use the table above, record the method per source, and test it with your own files. [1] [3]
Does Clams document hardware depreciation or mining-site profit?
Not on the pages reviewed. Clams does document mining-income categorization, cost basis from historical prices, and a Lightning node profitability report, which is not ASIC-site operating profit. Ask for a demo of an equipment register or site allocation if you need those. [3] [4] [5] [6]
Can Flash or Clams replace tax advice?
No. This is general information, not tax, legal or accounting advice. Confirm classifications with a qualified accountant in your jurisdiction.
Which mining pools connect directly in Flash?
Braiins Pool with a read-only API token; OCEAN Pool read-only through your public Bitcoin mining address; NiceHash mining earnings and wallet activity, including deposits, trades and withdrawals. Luxor and Foreman are CSV import only. [1]
Is Flash vs Clams a rating or a winner pick?
No. This is a founder-disclosed use-case comparison. Flash makes one of the tools listed. Choose by your ledger route, deployment needs and whether you need mining-site economics.
